Regular expression

How can i get just the last number in this list with a reg.exp?

If I have
[3][4][1][41][2] << i must get: 2
[3][4][1][41][274] << i must get: 274

How can i achieve that with a regular expression?

Personally i wouldn't use regular expressions for this. I would do something like this:

$last_open = strrpos($string,"[");
$last_close = strrpos($string,"]");
$length = ($last_close-$last_open-1);
$last_num = substr($string,$last_open+1,$length);

Thanks eelixduppy!
Only one thing, the strrpos() takes the string as first argument and the char as the second one.

Ooops...i guess that's what happens when you are doing 100 things at once :)
